    The improvements in healthcare systems and the advent of precision medicine initiative have created the need to develop more innovative manufacturing methods for the delivery of individualized dosing and personalized treatments. In recent years, the US Food and Drug Administration (FDA) introduced the Quality by Design (QbD) and Process Analytical Technology (PAT) guidelines to encourage innovation and efficiency in pharmaceutical development, manufacturing and quality assurance. As a result of emerging technologies and encouragement from the regulatory authorities, the pharmaceutical industry has begun to develop more efficient production systems with more intensive use of on-line measurement and sensing, real time quality control and process control tools, which offer the potential for reduced variability, increased flexibility and efficiency, and improved product quality

    The successful deployment of AI solutions in manufacturing environments hinges on their security, safety and reliability which becomes more challenging in settings where multiple AI systems (e.g., industrial robots, robotic cells, Deep Neural Networks (DNNs)) interact as atomic systems and with humans. To guarantee the safe and reliable operation of AI systems in the shopfloor, there is a need to address many challenges in the scope of complex, heterogeneous, dynamic and unpredictable environments. Specifically, data reliability, human machine interaction, security, transparency and explainability challenges need to be addressed at the same time. Recent advances in AI research (e.g., in deep neural networks security and explainable AI (XAI) systems), coupled with novel research outcomes in the formal specification and verification of AI systems provide a sound basis for safe and reliable AI deployments in production lines. Moreover, the legal and regulatory dimension of safe and reliable AI solutions in production lines must be considered as well. To address some of the above listed challenges, fifteen European Organizations collaborate in the scope of the STAR project, a research initiative funded by the European Commission in the scope of its H2020 program (Grant Agreement Number: 956573). STAR researches, develops, and validates novel technologies that enable AI systems to acquire knowledge in order to take timely and safe decisions in dynamic and unpredictable environments. Moreover, the project researches and delivers approaches that enable AI systems to confront sophisticated adversaries and to remain robust against security attacks. This book is co-authored by the STAR consortium members and provides a review of technologies, techniques and systems for trusted, ethical, and secure AI in manufacturing. The different chapters of the book cover systems and technologies for industrial data reliability, responsible and transparent artificial intelligence systems, human centered manufacturing systems such as human-centred digital twins, cyber-defence in AI systems, simulated reality systems, human robot collaboration systems, as well as automated mobile robots for manufacturing environments. A variety of cutting-edge AI technologies are employed by these systems including deep neural networks, reinforcement learning systems, and explainable artificial intelligence systems. Furthermore, relevant standards and applicable regulations are discussed. Beyond reviewing state of the art standards and technologies, the book illustrates how the STAR research goes beyond the state of the art, towards enabling and showcasing human-centred technologies in production lines. Emphasis is put on dynamic human in the loop scenarios, where ethical, transparent, and trusted AI systems co-exist with human workers. The book is made available as an open access publication, which could make it broadly and freely available to the AI and smart manufacturing communities

    Vision 2040: A Roadmap for Integrated, Multiscale Modeling and Simulation of Materials and Systems

    Over the last few decades, advances in high-performance computing, new materials characterization methods, and, more recently, an emphasis on integrated computational materials engineering (ICME) and additive manufacturing have been a catalyst for multiscale modeling and simulation-based design of materials and structures in the aerospace industry. While these advances have driven significant progress in the development of aerospace components and systems, that progress has been limited by persistent technology and infrastructure challenges that must be overcome to realize the full potential of integrated materials and systems design and simulation modeling throughout the supply chain. As a result, NASA's Transformational Tools and Technology (TTT) Project sponsored a study (performed by a diverse team led by Pratt & Whitney) to define the potential 25-year future state required for integrated multiscale modeling of materials and systems (e.g., load-bearing structures) to accelerate the pace and reduce the expense of innovation in future aerospace and aeronautical systems. This report describes the findings of this 2040 Vision study (e.g., the 2040 vision state; the required interdependent core technical work areas, Key Element (KE); identified gaps and actions to close those gaps; and major recommendations) which constitutes a community consensus document as it is a result of over 450 professionals input obtain via: 1) four society workshops (AIAA, NAFEMS, and two TMS), 2) community-wide survey, and 3) the establishment of 9 expert panels (one per KE) consisting on average of 10 non-team members from academia, government and industry to review, update content, and prioritize gaps and actions. The study envisions the development of a cyber-physical-social ecosystem comprised of experimentally verified and validated computational models, tools, and techniques, along with the associated digital tapestry, that impacts the entire supply chain to enable cost-effective, rapid, and revolutionary design of fit-for-purpose materials, components, and systems. Although the vision focused on aeronautics and space applications, it is believed that other engineering communities (e.g., automotive, biomedical, etc.) can benefit as well from the proposed framework with only minor modifications. Finally, it is TTT's hope and desire that this vision provides the strategic guidance to both public and private research and development decision makers to make the proposed 2040 vision state a reality and thereby provide a significant advancement in the United States global competitiveness

    Manufacturing High Entropy Alloys: Pathway to Industrial Competitiveness

    Full text link
    High entropy alloys (HEAs) provide a transformative opportunity to design materials that are custom tailored to the distinct needs of a given application, thereby shifting the paradigm from “apply the material you have” to “engineer the material you need.” HEAs will enable high-performance manufactured goods that are competitive in the international marketplace through extraordinary material properties and unique property combinations. HEAs deliver new choices to manufacturers to create alternatives to materials that are rare, hazardous, expensive, or subject to international restrictions or conflict. The potential benefits of HEAs span diverse fields and applications, and show promise to not only accelerate economic growth and domestic competitive advantage, but also address pressing societal challenges. These include solid state cooling, liquefied natural gas handling, nuclear degradation- resistant materials, corrosion-resistant heat exchangers, and efficiency gains from high temperature performance that advance national energy goals; high-performance aerospace materials and ultra- hardness ballistics that support national security; and strong, corrosion-resistant medical devices and advances in magnetic resonance imaging that are essential to national health priorities. Research advances are setting the stage to realize each of these vital areas. However, research advances made to-date to produce lab-scale prototypes do not lend themselves to manufacturing at scale. For Americans to fully benefit from HEAs, the emerging technologies must be translated into products manufactured at scale in the United States. However, manufacturers and HEA experts who are working to bridge this gap are encountering cross-cutting barriers in manufacturing processes, testing, data, and access to the necessary resources. Through strategic public- and private- sector research and investment, these barriers can be overcome. The United States has invested in both HEA research and advanced materials resources, such as material sample creation at the Ames Laboratory Materials Preparation Center, material characterization at Oak Ridge National Laboratory’s Neutron User Facilities, and modeling and analysis through the National Institute of Standards and Technology’s Material Genome Initiative. A vast array of research and expertise has been fostered at federal laboratories and universities, yielding promising alloys, manufacturing processes, and analysis methods.National Science Foundation, Grant No. 1552534https://deepblue.lib.umich.edu/bitstream/2027.42/146747/1/Manufacturing-HEAs.pdf-1Description of Manufacturing-HEAs.pdf : Main articl

Our extended senses, tools, technologies, through the ages, have been closed systems incapable of interplay or collective awareness. Now, in the electric age, the very instantaneous nature of co-existence among our technological instruments has created a crisis quite new in human history. Our extended faculties and senses now constitute a single field of experience which demands that they become collectively conscious. Our technologies, like our private senses, now demand an interplay and ratio that makes rational co-existence possible. As long as our technologies were as slow as the wheel or the alphabet or money, the fact that they were separate, closed systems was socially and psychically supportable. This is not true now when sight and sound and movement are simultaneous and global in extent. (McLuhan 1962, p.5, emphasis in original)Over forty years later, the seamless interplay that McLuhan demanded between our technologies is still barely visible. McLuhan’s predictions of the spread, and increased importance, of electronic media have of course been borne out, and the worlds of business, science and knowledge storage and transfer have been revolutionised. Yet the integration of electronic systems as open systems remains in its infancy.Advanced Knowledge Technologies (AKT) aims to address this problem, to create a view of knowledge and its management across its lifecycle, to research and create the services and technologies that such unification will require. Half way through its sixyear span, the results are beginning to come through, and this paper will explore some of the services, technologies and methodologies that have been developed. We hope to give a sense in this paper of the potential for the next three years, to discuss the insights and lessons learnt in the first phase of the project, to articulate the challenges and issues that remain.The WWW provided the original context that made the AKT approach to knowledge management (KM) possible. AKT was initially proposed in 1999, it brought together an interdisciplinary consortium with the technological breadth and complementarity to create the conditions for a unified approach to knowledge across its lifecycle. The combination of this expertise, and the time and space afforded the consortium by the IRC structure, suggested the opportunity for a concerted effort to develop an approach to advanced knowledge technologies, based on the WWW as a basic infrastructure.The technological context of AKT altered for the better in the short period between the development of the proposal and the beginning of the project itself with the development of the semantic web (SW), which foresaw much more intelligent manipulation and querying of knowledge. The opportunities that the SW provided for e.g., more intelligent retrieval, put AKT in the centre of information technology innovation and knowledge management services; the AKT skill set would clearly be central for the exploitation of those opportunities.The SW, as an extension of the WWW, provides an interesting set of constraints to the knowledge management services AKT tries to provide. As a medium for the semantically-informed coordination of information, it has suggested a number of ways in which the objectives of AKT can be achieved, most obviously through the provision of knowledge management services delivered over the web as opposed to the creation and provision of technologies to manage knowledge.AKT is working on the assumption that many web services will be developed and provided for users. The KM problem in the near future will be one of deciding which services are needed and of coordinating them. Many of these services will be largely or entirely legacies of the WWW, and so the capabilities of the services will vary. As well as providing useful KM services in their own right, AKT will be aiming to exploit this opportunity, by reasoning over services, brokering between them, and providing essential meta-services for SW knowledge service management.Ontologies will be a crucial tool for the SW. The AKT consortium brings a lot of expertise on ontologies together, and ontologies were always going to be a key part of the strategy. All kinds of knowledge sharing and transfer activities will be mediated by ontologies, and ontology management will be an important enabling task. Different applications will need to cope with inconsistent ontologies, or with the problems that will follow the automatic creation of ontologies (e.g. merging of pre-existing ontologies to create a third). Ontology mapping, and the elimination of conflicts of reference, will be important tasks. All of these issues are discussed along with our proposed technologies.Similarly, specifications of tasks will be used for the deployment of knowledge services over the SW, but in general it cannot be expected that in the medium term there will be standards for task (or service) specifications. The brokering metaservices that are envisaged will have to deal with this heterogeneity.The emerging picture of the SW is one of great opportunity but it will not be a wellordered, certain or consistent environment. It will comprise many repositories of legacy data, outdated and inconsistent stores, and requirements for common understandings across divergent formalisms. There is clearly a role for standards to play to bring much of this context together; AKT is playing a significant role in these efforts. But standards take time to emerge, they take political power to enforce, and they have been known to stifle innovation (in the short term). AKT is keen to understand the balance between principled inference and statistical processing of web content. Logical inference on the Web is tough. Complex queries using traditional AI inference methods bring most distributed computer systems to their knees. Do we set up semantically well-behaved areas of the Web? Is any part of the Web in which semantic hygiene prevails interesting enough to reason in? These and many other questions need to be addressed if we are to provide effective knowledge technologies for our content on the web

    Digital built Britain: level 3 building information modelling - strategic plan

    Get PDF
    [Ministerial Foreword] Construction is a sector where Britain has a strong competitive edge. We have world class capability in architecture, design and engineering and British companies are leading the way in delivering sustainable construction solutions. It is also a sector with considerable growth opportunities with the global construction sector forecast to grow by up to 70% by 2025. We are not starting from scratch. The Government in collaboration with industry has already committed to the Level 2 BIM programme as well as investing £220M in the development of a High Performance Computing programme and over £650M in the delivery of transformational high speed Broadband across the UK by 2015. We have a recent track record of world class construction deliveries such as the 2012 Olympics and Crossrail the largest construction project in Europe now reaching the half-way point. We have seen the global reaction to our Level 2 BIM programme’s successful delivery and significant cost savings which have greatly assisted the construction costs savings of £840M in 2013/4, with several major EU nations including France and Germany announcing similar BIM programmes. If we want to retain our strength in this economy we cannot stand by. We need concerted joint action from Government, Industry and Academia working in partnership toward the success of the sector and ensuring that benefits are felt across the rest of the economy. The Information Economy is transforming the way we live and work. It is crucial to our success on the global stage and to facing the challenges of urbanisation and globalisation that we grasp the opportunity that Digital Built Britain presents.
